%X Wireless sensor network systems have become revolutionize in recent years.Acoustic source Direction Of Arrival(DOA) is one of the essential phenomenon in manyapplications. Acoustic sensor network can provide a way to simulatenous monitor and interactionof many sources. This paper provides an preliminary study of Direction Of Arrival(DOA) foroutdoor positioning and attempt to classify the different approaches. We focus on DominantFrequency Selection(DFSE) ,Approximate Maximum Likelihood(AML) and Multiple SignalClassification(MUSIC) methods. We then illustrate and discuss the methods for Direction ofArrival.
